Gypsum is an ordinary material seen in everyday life. It is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O. It can be used as a fertilizer, is the main constituent in many forms of plaster and is widely mined. Early in ancient times, gypsum has been used in sculpture already.

 

How to Processing ?

 

After crushed by hammer crusher, the large Gypsum granula become small ones and are sent to storage hopper by elevator, and then evenly sent to the upper distribution plate of the turnplate by vibrating feeder and sloping feeding pipe.

 

When the 6-47 micron HGM100 Gypsum Pulverizing Machine is at work, all the grinding rollers are rolling in the ring, and the materials are driven to the edge of the turnplate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grinded by the rollers.

 

Then, the high-pressure air blower constantly inhales air within the 5-47 micron HGM100 Gypsum Pulverizing Machine and, in turn, the airflow with crushed materials are brought to the classifier whose high-speed impeller will screen the airflow: the unqualified particle size will fall and return to the mill for being reground while the qualified particle size mixed with air will go into the cyclone powder collector.
